What would you change in your school if you were a headmaster?

My school is an old and prestigious institution and I believe that many graduades, who may be famous politicians and successful business people, admit that they owe a lot to the unforgettable atmosphere and unique tradition of my school.

If I were a headmaster of my school, I`d make all members of this school community behave properly. I`d simply create some rules for students to obey:
no one would be allowed to smoke cigarettes in the lavatories or cloakrooms
they wouldn`t have to have their hair very short, but they would have to keep it clean and tidy
they would be able to eat at school, but eating during the lessons would be strictly forbidden
they wouldn`t have to change their shoes but they wouldn`t be allowed to bring mud and dirt into the school building
no one would be allowed to address teachers by their first names unless they were reckless enough to let them do so
they wouldn`t have to wear the school uniform but they would always have to wear the school tie
they wouldn`t have to pay for books but I would be glad if they bought coffee for the staff room

I`d also remind my students that they`re the youngest in the school and because of that their rights are limited. But I`d also tell them to cheer up, because days spent at school are very unforgettable days in our life.
